The function of elastic fibers in arteries is to do what?

Explanation:
Elastic fibers in arteries enable the vessel to stretch as the heart ejects blood during systole and then rebound during diastole. This stretch-and-recoil action smooths the blood flow and helps maintain arterial pressure between heartbeats, ensuring continuous perfusion. The other ideas don’t fit because elastic fibers aren’t for expanding capillaries, storing oxygen-rich blood, or producing lactic acid; their main role is providing elasticity to the arterial wall.
